Vectra® is an advanced blood test for rheumatoid arthritis (RA) disease activity. Vectra measures the levels of 12 protein biomarkers known to be important in RA and combines these levels into a single score, which can be used to provide a quantitative measure to objectively assess and track RA disease activity.
Personalizing Treatment Goals for Patients with Rheumatoid Arthritis
Regular, objective assessments of RA disease activity are critical for achieving target levels of disease activity and improving patient outcomes.1-7
Physicians typically use symptom assessments, joint evaluations and laboratory testing for C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR) to guide treatment goals for the management of RA. However, these measures cannot always identify underlying disease activity or accurately assess the risk of future joint damage, which may continue even when signs and symptoms appear to be controlled.8-10
Vectra simultaneously measures 12 key biomarkers associated with RA disease activity and combines them into a single score between 1 and 100 (where a lower score indicates less disease activity).
By providing an objective and reproducible measure of RA disease activity that can be used alongside existing assessment tools, Vectra helps patients with RA and their healthcare professionals to work together in determining individualized treatment goals.11,12
